Check if the same lab product or an alternative is used in the 5 most similar protocols
9-Phenanthrol was purchased from Toronto Research Chemicals (North York, Canada).
Atropine, carbachol, and nystatin were purchased from Wako (Osaka, Japan). L-NAME
(Nω-Nitro-L-arginine methyl ester hydrochloride), guanethidine, α, β-methylene ATP,
collagenase type II and type XI, papain, dithiothreitol, and bovine serum albumin were
purchased from Sigma-Aldrich Chemical Co. (St. Louis, MO, U.S.A.). 9-Phenanthrol was
dissolved in dimethyl sulfoxide (DMSO), where the final concentration of DMSO up to 0.03%
had no effect on EFS- or carbachol-evoked contractions.

Krebs' Solution Preparation for Tissue Experiments

Check if the same lab product or an alternative is used in the 5 most similar protocols
During experiments, tissues were maintained in Krebs’ solution consisting of (mM): NaCl 118.4, KCl 4.7, CaCl2 2.5, MgSO4 1.2, KH2PO4 1.2, NaHCO3 25 and glucose 11.7. ATP, tetraethylammonium chloride (TEA), tetrodotoxin, atropine sulfate monohydrate and carbachol were obtained from FUJIFILM-Wako (Osaka, Japan). D-tubocurarine, suramin, methoctramine hydrate, 4-diphenylacetoxy-N-methyl-piperidine methiodide (4-DAMP), pyridoxal phosphate-6-azophenyl-2,4-disulfonic acid (PPADS), cibacron blue F3GA (CBF3GA; synonym reactive blue 2) and 4-aminopyridine (4-AP) were obtained from Sigma-Aldrich (St Louis, MO, USA). Glibenclamide and nicorandil were obtained from Tokyo Chemical Industry (Tokyo, Japan). GSK1016790A was obtained from Cayman Chemical (Ann Arbor, MI, USA). Apamin was obtained from Peptide Institute (Osaka, Japan). tetrodotoxin was dissolved in citrate solution. Glibenclamide, nicorandil and GSK1016790A were dissolved in DMSO. Other drugs were dissolved in distilled water. The highest concentration of vehicles (0.1%) for the drugs alone had no effect on the basal tone and contractile responses at the concentrations used. The concentrations of drugs given were final concentrations in the bath solution.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
